Description

Radio link failure reporting method, information interaction method and equipment
Technical Field
The present invention relates to the field of wireless communication technologies, and in particular, to a method for reporting a radio link failure, a method for information interaction, and a device for information interaction.
Background
In an LTE (Long Term Evolution ) system, a UE may monitor RLF (Radio link failure), and there are various reasons for Radio link failure, for example:
1. t310timer expires;
2. t312timer expires;
3. receiving a random Access problem indicated by a Media Access Control (MAC) layer, wherein any one of timers (T300, T301, T304 and T311) is not operated;
4. the received RLC (Radio Link control) layer indicates that ARQ (Automatic Repeat-reQuest) reaches the maximum retransmission number.
In order to support mobile robustness optimization, an LTE system introduces a terminal radio link failure reporting mechanism in Rel-9 (version 9), and an indication carried in an RRC Connection Re-establishment Complete message indicates that RLF information needs to be reported. The Rel-10 (version 10) enhances the mechanism and content of radio link failure reporting, and adds an indication indicating that RLF reporting is available in an RRC Connection Setup Complete message and an RRC reconfiguration Complete message, and adds information such as location information, time information, and failure type in the content.
On The other hand, ITU (international telecommunications union) defines three major application scenarios of 5G (The 5th Generation mobile communications, fifth Generation mobile communications technology), and proposes a key index capability more challenging than 4G, requiring support of a peak rate of 100Gbps + and lower air interface delay (eMBB (enhanced mobile broadband) 4ms, URLLC (low-delay high-reliability connection) 0.5 ms). In order to achieve a peak speed several times faster than that of LTE, considering the current situation that the spectrum (lower than 6GHz) resource of the conventional wireless communication is seriously insufficient, 5G will probably use a spectrum resource (for example, the millimeter wave frequency band is above 10 GHz) much higher than that used in the conventional LTE to perform wireless communication, and in order to enhance the coverage, 5G will use a beamforming technology.
The reporting of the terminal RLF information plays an important role in network optimization, such as mobility optimization, coverage optimization, etc., but currently, the RLF report does not include related information of beam and SUL (Supplementary UPLink) introduced in 5G.

Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the drawings of the embodiments of the present invention. It is to be understood that the embodiments described are only a few embodiments of the present invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the described embodiments of the invention, are within the scope of the invention.
Taking the radio link failure due to the too late LTE handover as an example, please refer to fig. 1, the radio link failure reporting process is as follows: 1. the Radio link failure occurs in a source cell (of a source base station) before handover, and a UE (terminal) sends an RRC (Radio Resource Control) connection reestablishment Request (RRC connection Request) message to a target base station; 2. the target base station sends an RRC connection reestablishment (RRC connectionReestassignment) message to the UE; 3, the UE sends an RRC connection reestablishment completion (RRC connection request Complete) message to the target base station, wherein the RRC connection reestablishment completion message carries an indication that RLF reports; 4. a target base station sends a terminal Information Request (UE Information Request) message to UE, wherein the terminal Information Request message carries an RLF report (report) Request; 5, the UE sends a terminal Information Response (UE Information Response) to the target base station, carries an RLF report (RLF report) and contains RLF Information; 6. the target base station transmits an RLF indication (RLF indication) to the source base station.
In the target 3GPP protocol, the main contents included in the reported radio link failure information are shown in the following table:
table 1 shows the main contents contained in the radio link failure information reported
Figure BDA0001810879030000051
Figure BDA0001810879030000061
In the above table, the radio link failure information does not include information on the beam introduced in the 5G NR and information on the enhanced uplink (SUL). Therefore, to solve the technical problem, an embodiment of the present invention provides a method for reporting a radio link failure, please refer to fig. 2, where the method is applied to a terminal, and includes the following steps:
step 11: and reporting radio link failure information to network side equipment, wherein the radio link failure information comprises information of beams and/or information of uplink carriers.
In the embodiment of the present invention, the radio link failure information reported by the terminal to the network side device includes information related to a beam and/or information related to an uplink carrier. Thus, more information is provided for network optimization (including mobility optimization and coverage optimization, etc.). Wherein the uplink carriers include an uplink carrier and an enhanced uplink carrier, and the beam and the enhanced uplink carrier (SUL) are introduced in the 5G NR.
Specifically, the network side device may be a base station, and the terminal may initiate RRC reestablishment to a cell of another base station after a radio link failure occurs in a cell under one base station, or directly initiate RRC establishment to a cell of another base station after entering an idle state, and finally establish RRC connection with another base station. The base station that has finally established the RRC connection with the terminal may forward (through RLF indication) the radio link failure information to the base station that has failed the radio link after receiving the radio link failure information reported by the terminal.
The following exemplifies the above method for reporting radio link failure.
In an optional specific embodiment, the information of the beam includes at least one of:
an identification of a beam of a serving cell in which a radio link failure occurred;
measurement information of a beam of the serving cell;
an identifier of a beam of a neighbor cell of the serving cell;
measurement information of the beams of the neighbor cell.
Further, the measurement information of the beam includes: quality information of the beam.
Specifically, the quality information of the beam includes at least one of:

a reference signal reception quality based on CSI-RS measurements;
a signal to interference plus noise ratio based on the CSI-RS measurements.
Wherein the SS/PBCH Block (Synchronization Signal/Physical broadcast channel Block) includes a PSS (primary Synchronization Signal), an SSs (secondary Synchronization Signal), and a PBCH (Physical broadcast channel). The Chinese name corresponding to the CSI-RS is the channel state information reference signal.
In addition, the information of the uplink carrier includes at least one of:
absolute Radio Frequency Channel Number (ARFCN) of Uplink (UL) carrier;
absolute radio channel number of enhanced uplink (SUL) carrier.
In a mobile communication system, uplink data transmission and downlink data transmission can be simultaneously performed between a terminal and a base station, and since the transmission power of the base station is much higher than that of the terminal, a phenomenon that the downlink coverage area is larger than the uplink coverage area occurs. In a 5G high-frequency system, a base station uses a large-scale array antenna technology to enhance downlink coverage capability, so that the problem of uplink and downlink coverage imbalance is more serious. Therefore, a low frequency enhanced uplink (SUL) technique has been introduced to solve the problem of uplink and downlink coverage imbalance.
In the embodiment of the present invention, the information of the beam and the information of the uplink carrier included in the radio link failure information are not limited to the above-mentioned information, and may be some other information.
